To ,all whom it mayooncerm 'Beit known that I, SIMON GQLDNER, asub-ljecto'fthe King of Roumanie; residing at New v vYriarkgfborough ofManbattan,in the county and vState of New York, have invented 'new `nand useful Improvements in Mantles for Incandescent Lighting, ofwhichthe following is aspecieatio.

f These mantles,' called incandescent man- -tles for short, as known arequiterail and apt to break or crumble, and by means of this invention.the mantle can be.' reinforced or strengthenemasset forth in theyfollowing yspecification and cl .annexed drawings,y in which aims andillustrated in the Figure 1 is au elevation of the mantle. Fig.

2is a transverse section of Fig. l.

A n incandescent mantle is shown provided with a reinforcement whichtends'to make such mantle more durableand prevent shotl tering of thesame from vibrations. y

Thesemantles generally break at'the bulging portion below the neck. Thisneck portion of mantle 1 has the usual loop 2'for at-Y A taching to arod or support. Aboutthis loop 2 is coiled or connected a thin wire-such,

i' for exi-ample, as platinum. After being se cured toloopfthis wire or,lament v3 leads 'l intothe mantle, ypreferably centrally, forming thestem 4,' and at a suitable distance has a f number of lateral orradiating arms `5', ati tached to ring 6, the latter sitting snuglyagainst the interior o f the mantle. From the 'ring 6 depend a number orseries of wires 7.

The vbottom edge of the mantle is provided witha-tape or string 8, suchstrip 8 being 4pasted 'or secured round aboutsuch edge pori tion,landthe depending wires 7being. curved at their lowerendssuchcuryedportions can be made to vsit about the bottom edge of themantle'and clasp' the strip or tape 8. The. i

extra piece or string 8 atithe bottom'edge is practically made ofincombustible material, such as asbestos.

Such piece 'or reinforcement 8 tendsto hold the mantle in shapeand theseries of lower wires 7 being bent or clasped about the cord or edge 8support the lower part ofthe mantle to relieve the strain witnesses.

on the neck or upper part of fsnch mantle. A,Any suitable number o fWires can be used'foxl .tle in cylindrical or proper form and such 'wire6 or series 5, when made to rest on a burner, tends'to supportA themantle against breakage,besides' relieving the upper part of the mantlefrom weight or strain.

What I claim as new, and desire to" secure by Letters Patent, is-s' 1.'A mantle having a loop at its upper end,

la wire suspended centrally within the mantle rfrom said loop, a ringarranged in the vmantle and vsuspended from said wire, and verticalwires dependingfrom said ringand engaging the lower end of described. Yi 2. A mantle having a loo at its upper end, a wire suspended centrallyithinthe mantle from said loop, a ring arranged in the mantle andsuspended from said wireat a point inthe mantle, substantially astermediate the top and bottom of the mantle' `whereby the mantle is'held 'distended, and

kVertical wires depending from said ring and having hook-shaped 'lower'ends engagingl the lower edge of themen tle, substantially as described.1

, 3. A mantle havjnga loop at its upper end and a reinforcingtape at itslower edge, a

.wire suspendedcentrally Within the mantle from said'loop, al ringarranged in the mantle audsuspended Afrom said wire, 4anda pluralityof'1wires depending from said ring and having lhooked lower endsengaging the lower "edge of the mantle and said reinforcing-tape,

substantially asv described. Iu-testimonywhereof Ifhave hereunto set myhand in the presence of two subscribing y ,A Y i SIMON GOLDNER.
